Resolving a problem with journal cache or journal state - assure_mimix - 10.0

Problems with journal state or journal cache can cause the name of a data group to be highlighted on the Work with Data Groups display. If the data group name is highlighted in red or yellow, do the following to check for and resolve problems:

1. From the Work with Data Groups display, use option 8 (Display status).

2. From the Data Group Status display, press F8 (Database).

3. The Jrn State and Cache Src and Tgt fields are located In the upper left corner of the Data Group Database Status display. For each system (Src or Tgt) status of the journal state is shown first, followed by the status of the journal cache. The example below shows v for value in all for status positions. Based on the status displayed in these fields, you can take the actions described in the following steps to correct the problem:

   

4. Source system journal state (first Src: value) - If the source system state is red and the value for the journal state is standby (S) or inactive (I), the journal state must be changed and all data replicated through the user journal must be synchronized. Do the following:

   1. Press F12 (Cancel) to return to the Work with Data Groups display. Note which system is specified as the source system for the data group.

   2. Use option 45 (Journal Definitions) to view the journal definitions used for the data group in error.

   3. On the Work with Journal Definitions display, determine the journal name and library specified for the system that is the source system for the data group.

   4. Specify the name and library of the source system journal in the following command:

      CHJRN CHGJRN JRN(library/name) JRNSTATE(*ACTIVE)

   5. All data replicated through the user journal must be synchronized. For detailed information about synchronizing a data group, refer to your Runbook or to the Assure MIMIX Administrator Reference book.

5. Source system journal cache (second Src: value) - If the source system cache is yellow, the actual status does not match the configured value in the journal definition used on the source system. Do the following:

   1. Press F12 (Cancel) to return to the Work with Data Groups display. Note which system is specified as the source system for the data group.

   2. Use option 45 (Journal Definitions) to view the journal definitions used for the data group in error.

   3. On the Work with Journal Definitions display, use option 5 (Display next to the journal definition listed for the source system.

   4. Check the value of the Journal caching (JRNCACHE) parameter.

   5. Determine which value is appropriate for journal cache, the configured value or the actual status value. Once you have determined this, either change the journal definition value or change the journal cache (CHGJRN command) so that the values match.

6. Target system state(first Tgt: value) or Target system cache (second Tgt: value) - If the target system state or cache is yellow, the actual value for state or cache does not match the configured value. Do the following:

   1. Press F12 (Cancel) to return to the Work with Data Groups display. Note which system is specified as the target system for the data group.

   2. Use option 45 (Journal Definitions) to view the journal definitions used for the data group in error.

   3. On the Work with Journal Definitions display, use option 5 (Display next to the journal definition listed for the target system.

   4. Check the value of the following parameters, as needed:

      • Target journal state (TGTSTATE)

      • Journal caching (JRNCACHE)

   5. Determine why the actual status of the journal state or journal cache does not match the configured value of the journal definition used on the target system.

   6. Determine which values are appropriate for journal state and journal cache, the configured value or the actual status value. Once you have determined this, either change the journal definition value or change the journal state or cache (CHGJRN command) so that the values match.
